Sheet Metal Springs

Constant Torque Spring

A Constant Torque Spring is a type of torsion spring designed to deliver a uniform torque output throughout its range of motion. Unlike traditional torsion springs where torque varies with angle, constant torque springs provide steady rotational force regardless of how far they are wound or unwound. Key Features: Design: Made from a strip of spring steel or other metal tightly wound into a coil that unwinds under load, producing consistent torque Material: Typically manufactured from high-quality spring steel, stainless steel, or specialized alloys for durability and corrosion resistance Function: Provides smooth, continuous torque that remains nearly constant over the spring’s working range Durability: High cycle life and resistance to fatigue, suitable for repetitive motion applications Compactness: Efficient design allows for energy storage in a compact space
